Contus / WordPress Video Gallery – problems with sizes and widget search

Hi,I have two problems:

1o- I use in my homepage shortcodes “[categoryvideothumb type=category id=2 rows=1 cols=2]”
How I do to decrease the horizontal size and mainly the vertical between each video thumbnail?

2o- The widget “Contus video search” does not work, when I type the name of a video and click on the search, the right sidebar goes left and the rest of the page is blank.

Thanks and sorry my bad English
